STENCIL OR PERFORATING PEN.

SPECIFICATION forming part of Letters Patent No. 298,853, dated May 20, 1884,

(No model.)

To all whom it may concern:

Be it known that I, J OIIN O. HILL, a citizen of the United $tates, residing at New Guatemala, Guatemala, Central America, have invented Improvements in Stencil or Perforating Pens, in which the lower part of the needle passes through an eye in the foot of the machine, or through a tube, the foot supporting the weight of the machine, and the machine of peculiar shape to fit the hand when in position for writing.

These improvements are embodied in the mechanism illustrated in the accompanying drawings, in which Figure 1' is a side View of the machine, with one side of the frame taken off, showing the mechanism and shape of the machine. Fig. 2 is an end view of the machine complete. Fig. 3 is a view of the brake for stopping the machinery.

The coil-spring T is upon the same axle, h, with the wheel a, and, being fastened to the sides A A by the pin 26, furnishes the power for driving the mechanism. One end of the axleh extends beyond the side A and forms a stem to fit a key for winding up the coil spring. The wheel a connects with the small cog-wheel upon the axle of the wheel I), and sets it in motion. \Vheel b connects, in a similar manner, with wheel 0, and sets it in motion. The wheel 0, in turn, connects with the cog-wheel on the axle of the Cam .9, and sets in motion the wheel cl, which has con nection with the cog-wheel on the axle of the fan or regulator f, causing it to revolve, and also the wheel 0 sets in motion the cam s or crank-wheel a', which works in the hook or slot .of the upper extremity of the needle-bar iand gives a positive reciprocating movement to the needle or pen n.

It is apparent that the bearings of the several axles and pins are in the sides A A.

Extending out from the side A is the arm m, having an eye, 0, and through this the small upper end of the needle'bar passes, and the point of the needle or pen passes through the eye 9 in-the foot of the leg B. The leg B is firmly fastened to the pin it, which has bearings in the sides and has a foot upon which the weight of the hand and mech anism rests. The leg and foot are split and provided with screw Z, to open and close the same, for the purpose of changing the needle 7 and adjusting the size of the eye to the same.

The needle is secured to the needle-bar by the ordinary spring-c1amp, held together by a nut which permits the insertion and removal of needles and of gaging the depth of the punctures. The eyesoand 9 act as guides to the needle.

The bearing of the axle of wheel 02 extends through the side A, and upon this is the cap 1', and by pressing the-finger upon this cap the motion of the mechanism is stopped.

Through the side A extends the thumbpiece u of the brake b, fastened to the side A at v, the top having a mortise to receive the bent end of the spring t, which holds the brake in position, and near the foot an arm, ,2, to enter the" cogs of the wheel 0, the slot o permitting the operation of the brake. (See Fig. 3.)

To use this device I first wind it up with the key, like an ordinary clock. Then I take it in my hand, the side A toward my thumb,

in the same manner that I would take a pento write, and pressing the thumb downward upon the thumbpiece of the brake removes it, and the force of the spring starts the mechanism, and I proceed to write the stencil.

I stop the machinery, when writing, by pressing the finger upon the cap 0*.

Having thus fully described my invention, what I claim is 1. The combination of the leg and foot B, splitandprovided with the screw Z, securely attached to the pin is, with fixed rests in the sides A A, and needle 11., needle-bar i, and the mechanism described for operating the same, to provide a smooth rest for the mechanism, relieve the hand from supporting the weight and facilitate the making of perfect letters, as shown, and for the purposes specified.

2. The brake Z2, pinned to the side A, provided with a mortise on the upper end to receive the bent end of the spring t, and hav ing a thumb-piece extending out through the slot 1), and an arm, 2, to engage the cogs of the wheel a and stop the machinery and the needle, in combination with the wheel a, needlebar i, needle n, and the mechanism operating the same, as shown, and for the purposes specified.
